fix LLVM 3.4 build (bug #41061)
* configure.ac: Call new functions OCTAVE_LLVM_RAW_FD_OSTREAM_API and
OCTAVE_LLVM_LEGACY_PASSMANAGER_API, check for Verifier.h header file
* m4/acinclude.m4 (OCTAVE_LLVM_RAW_FD_OSTREAM_API): New function to
detect correct raw_fd_ostream API
* m4/acinclude.m4 (OCTAVE_LLVM_LEGACY_PASSMANAGER_API): New function
to detect legacy passmanager API
* libinterp/corefcn/jit-util.h: Use legacy passmanager namespace if
necessary
* libinterp/corefcn/pt-jit.h (class tree_jit): Use legacy passmanager
class if necessary
* libinterp/corefcn/pt-jit.cc: Include appropriate header files
* libinterp/corefcn/pt-jit.cc (tree_jit::initialize): Use legacy
passmanager if necessary
* libinterp/corefcn/pt-jit.cc (tree_jit::optimize): Use correct API
* libinterp/corefcn/jit-typeinfo.cc: Include appropriate header file
